(a) Olfactory neurons deploy a large specific surface area in the mucus through their cilia. To mimic this strategy, (b) Mascini et al. [103] modified ZnO nanoparticles with peptides, (c) Tanaka et al. [82] immobilized peptides specific to benzaldehyde on ZnO nanowires. (d) Jaffar-Bandjee et al. [108] fabricated artificial “moth antennae” (e) Gray et al. [109] proposed liposomes displaying tetrameric peptides to enable cooperative binding (f) Kotlowski et al. [96] used a bio-functional linker to optimize the orientation of OBPs on a graphitic surface.
